3770k @ 4.8Ghz = Full load is 244w ( 19.6Mhz per 1w of power )
Estimated 3770k @ 311w load = 6095Mhz
Really rough calculations here but will vary from chip to chip and will affected by Vcore.
4.8Ghz = 244w @ load
244w/4800Mhz = 0.05083
0.05083*6000Mhz = 305w of heat at load while running at 6Ghz
~305w would be on the absolute maximum a single stage can cope with safely, again this might increase depending the chip and the Vcore used, in could in theory be way above 300w
Single stage phase units pull roughtly 1:1 ratio of power to heat cooled.
So a 6Ghz Ivy would be 305w for the CPU + 305w for the phase unit
Total of 610w power consumption in a 'best case' scenario
But as already indicated by SDumper and FTW 420 a cascade system would more then likely need to be used to keep the cheap cool for 24/7 operation, these can consume way over 1000w under load.Single stage :
$500+ for the parts to make the single stage ( Not including labor )
~610w power consumptionCascade :
Up to $2000 for parts to make the system ( Not including labor )
1600w+ power consumptionDisclaimer
: All the above calculations are a load of crap because nothing ever scales quite so linear.
